FIELD: railway transport.
SUBSTANCE: springs 9 are installed in mirror-like manner relative to cross and longitudinal axes on supports of springs of central spring suspension of side 7 of frame bogie 6 by supports of lower support coils. Working and support coils of springs are made of plate or multiply plate containing plates of similar or different physical properties or hollow shaped section in form of flat spiral. Support coils of springs with supports in free state are made horizontally or at angle to horizon and are pointed in one direction or in different sides. Upper support coils of springs are connected, in mirror-like manner relative to cross and longitudinal axes, with supports of central spring suspension of bogie or body frame.
EFFECT: reduced overall dimensions and mass of central spring suspension, eliminated unbalanced end face moments, and misalignment of bogie frames and wheelsets.
